There is, there are and you can upgrade. :)
Buying the appropriate product is part of the problem you face.
Veritas has a brand new version of BackupExec, plus there is an open
file option available, as well as a bare metal product, intelligent
disaster recovery, etc.

Veritas also has a SQL connector to handle backups of MS SQL
databases. Plus, the normal process for databases is backing up the
database as a database management task within the database, then
backup the backup files to tape/disk/offline/whatever. Modern
databases have pretty decent disaster recovery options.

Which is good until restoration when you need to restore the original,
then each delta.

Veritas does backup-to-disk as well.

If you need a full system state backup every quarter hour, you should
likely have a live replicated server available.

If Asigra meets your needs it's a valid option. Go for it.
